Hi, i been having unexplained bruising around arms and thighs.i went to dr and had check up done that included blood clotting disorders, liver , hepatitis etc everything was normal. I continue to have unexplained bruises, just now one of the bruises its very painful. I could easily say I got over 5 bruises around thighs and like 3 on my arms. What could ne the cause of the unexplained bruising? I also have some dizziness at times when I lower my head anf memory loss . Im only 26 yrs old. Nothing at all seemed abnormal in routine lab test but the good cholesterol levels tjat were little low.

You need to be further investigated for the causes of that bruising. They can be caused by increased vascular fragility or problems with blood clotting. Please contact a hematologist for the same. There are several causes for clotting problems of blood.
